SPECIFICATION forming part of Letters Patent No. 446,752, dated February17', 18191.

Application iledlloveinbcr 8, 1890. Serial No. 370,782. (No model.)

.T0 @ZZ whom, it may concern.-

Be it known that we, JULIUS F. JAQUET, of Milwaukee, in the county ofMilwaukee and State of llliseonsin, and VILLIAM MCAUSLAN, of Brooklyn,in the county of Kings and State of New York, have invented a new andImproved Sidewalk, of which the following is a full, clear, and exactdescription. Y

This invention relates to improvements in sidewalks for streets or otherthoroughfares, and has for its objects to produce a sidewalk or pavementfor pedestrian travel which will be of a simple and durable constructionand which may be quickly put in place or be speedily detached forrepair, utilizing either wood or terra-cotta with metal as a materialfor its manufacture.

To these ends our invention consists in certain features of constructionand combinations of parts, asis hereinafter described and i claimed.

Reference is to be made to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a plan view of a supporting device for the tread-pieces ofthe sidewalk, which tread-pieces are shown broken and in dotted lines.Fig. 2 is a eross-section of the tread-pieces of a sidewalk and their supports, the latter being cuton the line 2 2 in Fig. l. Fig. 3 is a sideelevation of one ofthe bracket-stands used to support the treads of thesidewalk. Fig. t is an end View of the treadsupport shown in Fig. l,viewed in the direction of the arrow l in said figure. Fig. 5 is a planview of reduced size, showing the tread-pieces of the sidewalk insecured position on their supports. Fig. 6 is a side View in section oftwo broken sillvplates joined by a splice-bar.

Briefly considered, the improved sidewalk is composed of bracket-stands,which are arranged in series on elongated metal sills, whereon woodenplanks or terra-cotta slabs are secured by their interlocked engagementwith projections on the upper portions of the bracket-stands, theseveral b1'aeketstands of each series on a sill being suitably clampedtogether thereon. By provision of an indelinite number of such treads,sills, and stands a continuous, durable, and level wearing-surface isafforded of any desired width and length, as will appear in thefollowing detailedV description. The bracket-standsA are alike in forni.Hence a description of one will suffice for all shown, and asrepresented each stand consists of an upright flat plate a, having alianged base l), which is of such a proportionate length and width as toafford a 6o proper support for the material it is to sustain. Anydesired height is given to the bracket-standsA, and at or near the upperedge of the same on each side projecting tongues c are formed, which aresharpened toward their free edges. i Any desired number of the tongueformations are produced on the upright portions d of the bracket-stands,preferably opposite each other in pairs, and

at a proper distance from these tongues a 7o slot fl is formed in theupright a of each bracket-stand for the insertion of a sill B, that ispreferably made of metal in the shape of an elongated flat bar, whichwill loosely fit the transverse slot of each bracketstand, which slotsare parallel with the lower sur face of the bases l). It is equallyfeasible to extend the sills B across the sidewalk or longitudinally ofthe same. For illustration the first-named position will be assumed, asSo represented in Figs. l and 2, so that the pieces of wooden plank C,that are preferably used as treads for the sidewalk, will extendlengthwise of the walk, the length of the'similar bars or sills Brepresenting the width of said '85 sidewalk, which, it is apparent, maybe increased or diminished as may be required to suit the situation.

In constructing the sidewalk the surface of the ground isrendered'level, and, if neces- 9o sary for stability of the structure,flat stones or brick can be embedded in the ground to form a firmfoundation for the bracket-stands A.

A number of the sills B, similarly formed, are furnished for the supportof the planks C, which are placed upon said sills, that are evenlyspaced apart at a proper distance, so

as to afford a support for the tread-pieces named.

The parts of the sidewalk are assembled as loo follows: A sufiicientnumber of the wooden or tire-hardened earthenware tread-pieces C arelaid in position upon the sills B, so disposed that a row ofbracket-stands A will be located between and engage the edges of thejplanks oppositely, as shown in Fig. 2. rlhese stands are then clampedtoward each other, so as to embed the tongue c in corresponding notches'formed in the tread-pieces by providing an abutment-block D for eachsill, which blocks are secured upon the outer end portions of the sillsby bolts e or other means. At the opposite end of each sill B aclamping-block E is located. Said blocks, which are of similar form, incontour correspond with the shape ot' the upper portion ot thebracket-stands A, and are each slotted transversely near the lower end,producing 'apertures of a form. corresponding to that ot the sills vandof suoli relative dimensions thereto that the clamping-blocks when inplace may be wedged fast by the introduction inthe slots of tapering'keys g, as shown in Fig. 2, the laction of the clamping-blocks whendriven against the 'upper ends of the bracketstands serving to draw allintermediate stands and engaged tread-'pieces A in Aclose contact andlock them to the sills.

The interpositfion of the bracket-standsbctween theradjacent edges ofthe tread-pieces A produces crevices between said pieces, so

that rain or melted snow will not remain on' the treads, butw'illvescape between them, and, as there are elongated apertures 7L formed inthe sills B, these pieces are therebylightened in weight and adapted topermit `air to have access to the m aj or portion of the treadpiecesimposed 'on them.

Vhen the sidewalk is constructed to extend the tread -pieces Alongitudinally and their supporting 4devices across the walk, as isrepresented in Figs. l and 2, the ends of aligning plank or terra-cottaslabs should rest upon a sill, as shown in dotted lines in Fig. l, andmay break joints, which will render the suryfacesmooth'and prevent theplank ends from 'sagging or twisting, the free accessof air to thewooden plank on the sides and edges aiding the retention of the materialin an unwarped condition. Should the sidewalk 'be arranged to extend thesills B longitudinally instead of transversely, these sills must then bejoined together at their ends, as shown in Fig. 5, a splice-bar 3 beingplaced below the joint and secured to the sillsby bolts, so that anindefinite length of continuous sills may thus be provided and the plankor terra-cotta slabs secured transversely thereon in an ob` Vi-ousmanner.

At desired points the abutmentblocks D may be provided with rings m forthe hitching of horses, which rings'inaybe formed with the blocks or besecured thereto by a threaded engagement, as shown in Fig. 2.

Having thus described our invention,what we claim as new, and desire-t0secure by Letters Patent, is

l. Asidewalk composed of similar bracket stands, each similarlyapertured sidewise and provided` with enlarged bases and lateral tongues onopposite sides above theapertu-res, elongated sills whichslide in theapertures of the bracket-stands, tread-pieces having` parallel edgeswhich are located intermediately of the bracket-stands on the sills a-ndadapted to interlock -wi th the tongues o-n the bracketstands, anabutmentblock onfon-e endfof each sill, and clamping-blockswhich-holdthe treadpieces and bracketstands clamped against the abutment blocks,substantially as set forth.

2. In a sidewalk, t-he combination, with a series of similar'bracket-stands laterallyapertured to receive tlat elongated sills and aseries of elongated and perforated sills, lof a series of tread-pieceslocated on the lsills between the bracket-stands and interlocked withtongues that oppositely project from the s-ides ofthe bracket-stan ds,an abutment-block secured on one end of each sill, slidingclamping-blocks on the opposite ends of said sills, and tapering keysthat are adapted to bindv the clam ping-blocks on the sills,substantially as set fort-h.
